- connection apparatus and system described in this document comprises components which may not conform to the traditional definition of a socket, jack or plug.
- the terms “socket” and “jack” are used to refer generally to a connector component which is connected to a communication system or a media delivery device or system for example, and the term “plug” is used to refer to a connector component which is typically attached to a device used by a user, such as a headset for example.
- the invention is not intended to be limited to that application. Therefore, it should be appreciated that the invention is applicable to connector apparatus in general, and includes within its scope connector apparatus for use in communication systems such as “SKYPE” headsets and/or mobile telephone connection devices and/or MP3 media delivery device charging interfaces or connectors amongst other various applications.
- a socket is shown generally referenced 1 .
- the front elevation shown in the drawing reveals the front face of the socket as it would appear ready to receive a “plug” of a connector.
- the socket construction as shown in FIG. 1 is an example of an existing socket which may be used in conjunction with a noise canceling headset. Therefore, the socket as shown in FIG. 1 is one which can be used with an existing form of plug, i.e. being capable of receiving one, two, or up to three pins of an existing plug construction, but which is also adapted to receive an alternative form of plug which is held in place by virtue of magnetic means which act between the socket and the plug, as will be described further below.
- the invention as described below may also be implemented in a socket and/or plug construction which does not provide the existing conventional plug pin and plug pin receiver construction.
- the socket 1 includes a housing 2 which supports three pin receiving sockets 3 .
- the housing has a face 4 .
- face 4 comprises part of a contour in the housing defined by raised edge 5 which may be used to facilitate correct interconnection between the socket and the plug, as will be described further below.
- a magnetic means comprising one or more magnets 6 which are diagrammatically represented in FIG. 1 for purposes of explanation despite not normally being visible.
- magnets 6 are diagrammatically represented in FIG. 1 for purposes of explanation despite not normally being visible.
- magnets can be provided in different positions, other than those shown. Magnetism may be conducted through metal contacts to facilitate magnetic fields suiting connection to the plug whilst minimizing the of volume socket.
- the material which is used may simply be a magnetically permeable material i.e.
- magnetic means 6 may comprise magnets which act on magnetically permeable material (rather than a magnet per se) which is provided in or on a plug adapted for connection with the socket 1 .
- Conductor contact regions 7 are in this embodiment provided to allow the required number of contacts to adequately support a noise canceling headset.
- Conductor contact regions 8 may provide a power supply for operation of a device such as a noise canceling headset.
- the contacts 7 and 8 are provided such that they are exposed conductors adapted to make electrical connection with appropriate conductor contacts disposed in similar locations on the plug which is adapted for connection to the socket 1 . Therefore the contacts 7 and 8 are provided in front of the magnetic means 6 . This is shown more clearly in FIG. 3 . Further the contact regions 7 and/or 8 may provide dedicated contacts for connection to telephony (Voice over IP) headsets and other communication equipment.
- FIG. 3 the housing face 4 is shown, and it can be seen that above the housing face 4 a conductive layer 10 is provided.
- Layer 10 is configured to be connected at its periphery (not shown) or at another convenient location, with the appropriate conductors within the housing 2 for the electrical connections required to enable operation of the socket.
- This conductive layer 10 is shaped, or has an appropriate insulating region to enable the plurality of contact regions to be provided.
- the physical dimensions or extent of contact areas 7 and 8 can be defined by applying a non-conductive (and preferably appropriately cosmetic) layer 11 which therefore defines the required shape of each of the contact regions 7 and 8 .
- the face 4 may be constructed such that the connector regions project above a surrounding insulated region.
- the connector regions may comprise spring contacts, as will be described further below with reference to FIGS. 4 to 7 .
- a detector is included in the socket, so that when a plug is correctly connected to the socket, then the power supply is made available to contact regions 8 so that the supply can be used by the plug. Otherwise, the power supply is not available at contact regions 8 for safety purposes. This can be achieved by a mechanical switch for example, or alternatively, by electrically detecting connection of the plug with the socket or by using impedance detection circuitry to detect the nature of the connection made.
- the contacts 7 may be used to electrically detect the presence of the plug, and in another embodiment the presence of a plug pin within a pin receiver of the socket may be used to perform the detection step.
- the contact regions 8 may be recessed sufficiently so as to make inadvertent shorting or other electrical contact unlikely.
- the conductive layer 10 and the non-conductive layer 11 may be constructed as “decals” which are easily manufactured and attached to body 2 of a socket 1 during a manufacturing process.
- the outer contour of the face 4 may be used to ensure that a correct alignment is achieved between the socket 1 and an appropriate plug. Therefore, the plug (not shown) may include a recess which corresponds with edge 5 to ensure a correct alignment is achieved in use between the socket and the plug. Alternatively or additionally, other alignment contours may be used to ensure that not only is alignment between the socket and plug correct, but also that the orientation of the plug is correct relative to its socket.
- the plug is shown generally referenced 20 , having housing 22 .
- the housing includes an opening 24 to allow a lead or cable to be connected to the housing.
- the housing contains one or more magnetic means such as magnets or magnetically permeable material, as discussed above in relation to the socket 1 .
- the magnet means is provided rearwardly of contacts 28 .
- the upper surface 26 of the plug 20 includes a number of contacts 28 .
- the contacts 28 comprise spring contacts i.e.
- the contacts project beyond surface 26 and are biased outwardly, but capable of being pressed back toward surface 26 on contact with the connector regions of the socket.
- the upper surface 26 also includes one or more alignment means which include contours and such as projecting portions and/or stubs 32 .
- the contours 28 can locate about outer surfaces of the peripheral edge 5 of the connector, and the stubs 32 may be provided within the pin receivers 3 .
- the stubs 32 could also include some form of communication connection (i.e. include one or more conductors) and/or may also include one or more magnetic means.
- the socket may include conventional functionality including pin receivers 3 for receiving pins of one or more known headset plugs.
- the socket has magnetic areas 42 . In a preferred embodiment these comprise permanent magnets (for example rare earth magnets), but in other embodiments may simply be ferromagnetic material for co-acting with a magnet or magnets in similar areas on a plug.
- the apparatus is generally referenced 40 and has a housing 41 . Associated with the housing 41 are locating projections 45 and a controllable location projection 46 . The function of these features will be described further below.
- a plurality of conductor contact regions arranged in a group 43 is provided. These are shown in more detail in FIG. 11 .
- the individual regions are labeled 1 to 10 in that figure and an example of an appropriate function for each electrical contact region in the context of an audio headset is also illustrated in FIG. 11 .
- the individual regions are arranged in three rows, the regions in the first and third rows being substantially aligned with each other, (i.e. regions 1 , 2 , 3 and 8 , 9 , 10 ) and the second or middle row (i.e. regions 4 , 5 , 6 and 7 ) has contact regions that are offset from the first and third rows.
- the region bounded by the contact regions 43 has a distinctive shape which may be adapted for receiving a part of the plug, as described further below.
- the shape thus helps to ensure that the plug and the socket can be aligned in only one way and therefore the correct contacts are made between the plug and the socket.
- FIGS. 12 to 14 A plug for use with the socket of FIGS. 8 to 10 is shown in FIGS. 12 to 14 .
- the plug which is referenced 50 , has a cord 53 and has projections 32 if required to assist with alignment with the socket.
- Magnets or magnetic regions 52 are provided to co-act with the magnets or regions 42 of the socket.
- a plurality of pins 51 is arranged in appropriate rows as described with reference to the plurality of contact regions 43 of the socket.
- the array of pins 51 may project slightly as shown in FIG. 13 for reception in an appropriately contoured recess of the socket.
- the pins 51 may comprise spring contacts which are biased to project but can move axially back toward the body of the plug upon contact with the socket.
- an armrest 49 such as an aircraft seat armrest, which may include a connector 48 that forms a part of the aircraft or vehicle IFE system.
- the socket 40 is engaged in the armrest and the plug 44 may be engaged with the connector 48 .
- FIGS. 16 to 19 an installation process for the socket 40 into armrest 49 is illustrated.
- the location projections 45 engage with the lower part of a cutout in the armrest 49 .
- the projection 46 is lowered by using an Allen Key or other appropriate tool to rotate projection 46 through use of the tool receiving socket 47 .
- the projection 46 is moved so that it projects from the housing and prevents the socket 40 from being removed from the armrest 49 , as shown in FIG. 19 .
- FIG. 20 A further embodiment of socket is shown in FIG. 20 in which the group 43 of conductor contact regions is has a different physical form, but comprises three rows of conductor contact regions which are provided adjacent to each other in the same plane.
- the group 43 is substantially flush with the surrounding portion of face 4 so that there is no lip or ridge about which dirt or grime can accumulate and thus cause a malfunction.
- FIGS. 21 and 22 show an arrangement of printed circuit boards 60 , 61 and 62 which may be used with an embodiment such as that of FIG. 20 .
- Circuit board 60 has a conductor layer that provides the group 43 of conductor contacts and is machined so that the group 43 protrudes from the remainder of the board. In this way, the housing can be located about the board 60 so that the group 43 is substantially flush with face 4 upon assembly.
- Board 60 also facilitates location of boards 61 and 62 which carry plug pin receivers 3 .
- the examples described above may be used in conjunction with an in-flight entertainment system the socket being provided in or adjacent to a passenger seat, and the plug being provided on a headset.
- the socket is intended to have a very long service life.
- Spring contacts which may be used with magnetic jacks by contrast have a limited lifetime.
- the plugs are part of headphones which are viewed by airline operators as a consumable device. Therefore where spring contacts are used they can be located on the plug to maximise the lifetime of the conductive surface of the socket.
- the construction shown has the advantage that multiple contact areas are provided using the layer structure disclosed, so that maximum use is made of the available space and therefore the overall size of the connector and plug arrangement can be kept to a minimum.
- the magnetic connection is advantageously achieved a magnetic means provided rearwardly of the connector regions i.e. the connector regions in use become between the magnetic means provided in the socket and the plug.
- the socket is provided which may still be used with “legacy” plug arrangements. Therefore, the socket supports a new magnetic plug, but also has the advantage it is functional with existing pin type plug constructions.

Abstract
Description
- 1. Field of the Invention
- This invention relates to connector apparatus. The invention is directed particularly, but not solely, to connector apparatus for making electrical connection between a media source and media delivery equipment, for example, an audio signal connection between apparatus such as a headset and an audio signal source such as that provided by an in-flight entertainment system.
- 2. Background
- Conventional connectors typically comprise a socket, and a plug which is received in the socket. For example, in an airline cabin, an in-flight entertainment system may provide media such as audio and video information to passenger seat locations, so that it is available to passengers. The video information is typically made available via a visual display unit located on the rear of a seat immediately in front of the passenger. Audio information is typically provided via a connector socket (sometimes referred to as a jack) which is provided adjacent to the seat, for example, being provided in the arm rest. The user is typically provided with a headset which has a plug which is received in the socket, so that the audio information is delivered to the headset.
- A problem can occur when tension is applied the headset plug. If the tension is applied in a direction so as to pull the plug axially from the socket, then no damage will usually occur. However, if tension is supplied in a direction other than the axial direction, such as a perpendicular direction, then breakage may occur. This is because the plug typically includes one or more elongate pins which are received in the socket. Unless the plug pins are removed in an axial direction, then there is a risk that the plug pins can break. This is often a problem within aircraft cabins, since a headset, or headset cable, can frequently be moved unintentionally. One example is a situation in which a passenger forgets that the headset is still being worn and rises from his or her seat, causing the headset cable to violently pull the plug from the socket. Another example is when an object is being moved in the vicinity of the seat, for example, a pillow or food tray which may catch on the headset cable, causing the plug to be torn from the socket.
- It is an object of the present invention to provide an approved connector apparatus, or to at least provide connector apparatus which provides a useful alternative to known connector apparatus or systems.

FIGS. 2 , 5, 6, 8, 11, 12, 20 of the accompanying drawings. - Further aspects of the invention will become apparent from the following description.
- Those skilled in the art will appreciate that the words “socket” or “jack”, and “plug” are used for the purposes of convenience, since the connection apparatus and system described in this document comprises components which may not conform to the traditional definition of a socket, jack or plug. Instead, the terms “socket” and “jack” are used to refer generally to a connector component which is connected to a communication system or a media delivery device or system for example, and the term “plug” is used to refer to a connector component which is typically attached to a device used by a user, such as a headset for example.
- Although the embodiments discussed below are referred in the context of audio delivery apparatus such as headsets and noise canceling headphones, the invention is not intended to be limited to that application. Therefore, it should be appreciated that the invention is applicable to connector apparatus in general, and includes within its scope connector apparatus for use in communication systems such as “SKYPE” headsets and/or mobile telephone connection devices and/or MP3 media delivery device charging interfaces or connectors amongst other various applications.
- Referring to
FIG. 1 , a socket is shown generally referenced 1. The front elevation shown in the drawing reveals the front face of the socket as it would appear ready to receive a “plug” of a connector. Those skilled in the art will appreciate that the socket construction as shown inFIG. 1 is an example of an existing socket which may be used in conjunction with a noise canceling headset. Therefore, the socket as shown inFIG. 1 is one which can be used with an existing form of plug, i.e. being capable of receiving one, two, or up to three pins of an existing plug construction, but which is also adapted to receive an alternative form of plug which is held in place by virtue of magnetic means which act between the socket and the plug, as will be described further below. Those skilled in the art will appreciate that the invention as described below may also be implemented in a socket and/or plug construction which does not provide the existing conventional plug pin and plug pin receiver construction. - Therefore, referring still to
FIG. 1 , thesocket 1 includes ahousing 2 which supports threepin receiving sockets 3. The housing has aface 4. In the embodiment shown,face 4 comprises part of a contour in the housing defined by raisededge 5 which may be used to facilitate correct interconnection between the socket and the plug, as will be described further below. - Located behind
face 4 of the plug (i.e. within the housing) is a magnetic means comprising one ormore magnets 6 which are diagrammatically represented inFIG. 1 for purposes of explanation despite not normally being visible. Those skilled in the art will appreciate that only a single magnet need be provided in some embodiments, and that more than two magnets can be provided in other embodiments. It will also be appreciated that magnets can be provided in different positions, other than those shown. Magnetism may be conducted through metal contacts to facilitate magnetic fields suiting connection to the plug whilst minimizing the of volume socket. Furthermore, those skilled in the art will appreciate that, rather than being magnetized, the material which is used may simply be a magnetically permeable material i.e. a material which facilitates a magnetic attraction with a magnet or magnetized material provided in a plug, for example. Alternatively,magnetic means 6 may comprise magnets which act on magnetically permeable material (rather than a magnet per se) which is provided in or on a plug adapted for connection with thesocket 1. - Referring now to
FIG. 2 , the socket ofFIG. 1 is again illustrated, but this time showing contact (i.e. electrical conductor or terminal) regions onface 4.Conductor contact regions 7 are in this embodiment provided to allow the required number of contacts to adequately support a noise canceling headset.Conductor contact regions 8 may provide a power supply for operation of a device such as a noise canceling headset. Thecontacts socket 1. Therefore thecontacts magnetic means 6. This is shown more clearly inFIG. 3 . Further thecontact regions 7 and/or 8 may provide dedicated contacts for connection to telephony (Voice over IP) headsets and other communication equipment. - Turning now to
FIG. 3 , thehousing face 4 is shown, and it can be seen that above the housing face 4 aconductive layer 10 is provided.Layer 10 is configured to be connected at its periphery (not shown) or at another convenient location, with the appropriate conductors within thehousing 2 for the electrical connections required to enable operation of the socket. Thisconductive layer 10 is shaped, or has an appropriate insulating region to enable the plurality of contact regions to be provided. The physical dimensions or extent ofcontact areas layer 11 which therefore defines the required shape of each of thecontact regions - Alternatively, rather than the construction shown in
FIGS. 2 and 3 , those skilled in the art will appreciate that theface 4 may be constructed such that the connector regions project above a surrounding insulated region. For example, the connector regions may comprise spring contacts, as will be described further below with reference toFIGS. 4 to 7 . Regarding thepower supply contacts 8, in one embodiment, a detector is included in the socket, so that when a plug is correctly connected to the socket, then the power supply is made available to contactregions 8 so that the supply can be used by the plug. Otherwise, the power supply is not available atcontact regions 8 for safety purposes. This can be achieved by a mechanical switch for example, or alternatively, by electrically detecting connection of the plug with the socket or by using impedance detection circuitry to detect the nature of the connection made. Thus in one embodiment thecontacts 7 may be used to electrically detect the presence of the plug, and in another embodiment the presence of a plug pin within a pin receiver of the socket may be used to perform the detection step. Alternatively, thecontact regions 8 may be recessed sufficiently so as to make inadvertent shorting or other electrical contact unlikely. - In one embodiment, the
conductive layer 10 and thenon-conductive layer 11 may be constructed as “decals” which are easily manufactured and attached tobody 2 of asocket 1 during a manufacturing process. - Furthermore, the outer contour of the
face 4, as defined byedge 5 may be used to ensure that a correct alignment is achieved between thesocket 1 and an appropriate plug. Therefore, the plug (not shown) may include a recess which corresponds withedge 5 to ensure a correct alignment is achieved in use between the socket and the plug. Alternatively or additionally, other alignment contours may be used to ensure that not only is alignment between the socket and plug correct, but also that the orientation of the plug is correct relative to its socket. - Referring now to
FIGS. 4 to 7 , one embodiment of a plug which may be used with the socket of the preceding figures is illustrated. Referring to those figures, the plug is shown generally referenced 20, havinghousing 22. The housing includes anopening 24 to allow a lead or cable to be connected to the housing. Although not shown inFIGS. 4 to 7 , the housing contains one or more magnetic means such as magnets or magnetically permeable material, as discussed above in relation to thesocket 1. In one embodiment, the magnet means is provided rearwardly ofcontacts 28. Theupper surface 26 of theplug 20 includes a number ofcontacts 28. In this example, thecontacts 28 comprise spring contacts i.e. the contacts project beyondsurface 26 and are biased outwardly, but capable of being pressed back towardsurface 26 on contact with the connector regions of the socket. Those skilled in the art will appreciate that other forms ofcontact 28 may be provided. theupper surface 26 also includes one or more alignment means which include contours and such as projecting portions and/orstubs 32. In use, thecontours 28 can locate about outer surfaces of theperipheral edge 5 of the connector, and thestubs 32 may be provided within thepin receivers 3. Those skilled in the art will appreciate that other arrangements are possible, and that thestubs 32 could also include some form of communication connection (i.e. include one or more conductors) and/or may also include one or more magnetic means. - Turning to
FIGS. 8 to 10 , a second embodiment of a socket is illustrated. Again, the socket may include conventional functionality includingpin receivers 3 for receiving pins of one or more known headset plugs. The socket hasmagnetic areas 42. In a preferred embodiment these comprise permanent magnets (for example rare earth magnets), but in other embodiments may simply be ferromagnetic material for co-acting with a magnet or magnets in similar areas on a plug. The apparatus is generally referenced 40 and has ahousing 41. Associated with thehousing 41 are locatingprojections 45 and acontrollable location projection 46. The function of these features will be described further below. - As can be seen, a plurality of conductor contact regions arranged in a
group 43 is provided. These are shown in more detail inFIG. 11 . The individual regions are labeled 1 to 10 in that figure and an example of an appropriate function for each electrical contact region in the context of an audio headset is also illustrated inFIG. 11 . It can be seen that the individual regions are arranged in three rows, the regions in the first and third rows being substantially aligned with each other, (i.e.regions regions contact regions 43 has a distinctive shape which may be adapted for receiving a part of the plug, as described further below. The shape thus helps to ensure that the plug and the socket can be aligned in only one way and therefore the correct contacts are made between the plug and the socket. - A plug for use with the socket of
FIGS. 8 to 10 is shown inFIGS. 12 to 14 . As with the previous embodiment, the plug, which is referenced 50, has acord 53 and hasprojections 32 if required to assist with alignment with the socket. Magnets ormagnetic regions 52 are provided to co-act with the magnets orregions 42 of the socket. A plurality ofpins 51 is arranged in appropriate rows as described with reference to the plurality ofcontact regions 43 of the socket. The array ofpins 51 may project slightly as shown inFIG. 13 for reception in an appropriately contoured recess of the socket. Thepins 51 may comprise spring contacts which are biased to project but can move axially back toward the body of the plug upon contact with the socket. - Turning to
FIG. 15 , anarmrest 49 is shown such as an aircraft seat armrest, which may include aconnector 48 that forms a part of the aircraft or vehicle IFE system. Thesocket 40 is engaged in the armrest and theplug 44 may be engaged with theconnector 48. - In
FIGS. 16 to 19 , an installation process for thesocket 40 intoarmrest 49 is illustrated. As can be seen, thelocation projections 45 engage with the lower part of a cutout in thearmrest 49. Theprojection 46 is lowered by using an Allen Key or other appropriate tool to rotateprojection 46 through use of thetool receiving socket 47. Once thesocket 40 is in place, theprojection 46 is moved so that it projects from the housing and prevents thesocket 40 from being removed from thearmrest 49, as shown inFIG. 19 . - A further embodiment of socket is shown in
FIG. 20 in which thegroup 43 of conductor contact regions is has a different physical form, but comprises three rows of conductor contact regions which are provided adjacent to each other in the same plane. In this embodiment thegroup 43 is substantially flush with the surrounding portion offace 4 so that there is no lip or ridge about which dirt or grime can accumulate and thus cause a malfunction. -
FIGS. 21 and 22 show an arrangement of printed circuit boards 60, 61 and 62 which may be used with an embodiment such as that ofFIG. 20 . Circuit board 60 has a conductor layer that provides thegroup 43 of conductor contacts and is machined so that thegroup 43 protrudes from the remainder of the board. In this way, the housing can be located about the board 60 so that thegroup 43 is substantially flush withface 4 upon assembly. Board 60 also facilitates location of boards 61 and 62 which carryplug pin receivers 3. - The examples described above may be used in conjunction with an in-flight entertainment system the socket being provided in or adjacent to a passenger seat, and the plug being provided on a headset. The socket is intended to have a very long service life. Spring contacts which may be used with magnetic jacks by contrast have a limited lifetime. The plugs are part of headphones which are viewed by airline operators as a consumable device. Therefore where spring contacts are used they can be located on the plug to maximise the lifetime of the conductive surface of the socket.
- Those skilled in the art will appreciate that the construction shown has the advantage that multiple contact areas are provided using the layer structure disclosed, so that maximum use is made of the available space and therefore the overall size of the connector and plug arrangement can be kept to a minimum. The magnetic connection is advantageously achieved a magnetic means provided rearwardly of the connector regions i.e. the connector regions in use become between the magnetic means provided in the socket and the plug. Furthermore, those skilled in the art will appreciate that the socket is provided which may still be used with “legacy” plug arrangements. Therefore, the socket supports a new magnetic plug, but also has the advantage it is functional with existing pin type plug constructions.
